CLOTHES-WRINGER.

SPECIFICATION forming part of Letters Patent No. 287,782, dated October30, 1883.

Application filed May 16,1883. (No model) I To all whom it may concernBe it known that 1, CHARLES K. STINSON, a citizen of the United States,residing at Boston, in the county of Suffolk and State .ofMassachusetts, have invented certain new and useful Improvements inClothes-WVi-ingers; and I do hereby declare that the same are fullydescribed in the following specification and illustrated in theaccompanying drawings.

The object of this invention is .to produce a wringing or squeezingmachine in which,

without the employment of adjusting-screws, the pressure can be put'upon the rollers to force them together, and upon the tub to secure themachine in position for use, and also that both these pressures can beinstantly and simultaneously relaxed when desired; To accomplish theseobjects,the machine itself, other than the clamping device, is madealever, and is turned or swung forward and back upon the pivots by whichit issecured to its clamps. These movements so change the relation ofthe roller-bearings to each other and to the clamps as to give powerfulpressures in the one position and wholly relax them in the other.

The peculiarities of the invention are indicated in the drawings,explained in the description, and specifically stated in the claims.

In the drawings, Figure 1 is a perspective View, showing one end of themachine in its working position with the rolls under press ure. Fig. 2is anend elevation with the pressure relaxed, showing also an adjustableclamp such as I prefer to use for set-tub wringers. Fig. 3 is afrontview, on a smaller scale, of the end of the machine. 7

The pressure-rollers A'B are mounted'in a frame composed, essentially,of two vertical end pieces, 0, and two curved springs, D,

O. 4 by a cross-bar, E. These seven parts are caused to move together asone on pivots H, which connect the end pieces, 0, to the tub clamps, andit is this movement forward and back which applies and relaxes thepressure in' the use of the machine.

Each of the end pieces, 0, has a flattened projection, O,to'which thelower end of the spring 1) is seen red by the bolt F, which also rigidlyconnected lengthwise of the machine'- 1 passes through the end of thecross-bar E, and

is held in place bya nut, G. The upper roller I has its bearings inconcavities d,'formed for the purpose at the upper ends of the springsD. The upper part of each end-piece, O, is also concaved, as at c, tobear against the 5 projecting shaft or spindle of the upper roll, whilethe shafts of the lower roller pass through slots Sin the end pieces,and have their principal bearings upon one of the pivoted clampbars. l

The clamping device (connected to the machine, as above described, bypivots H) con sists, essentially, at each end of the machine, of twoclamp-bars, J J and K, pivoted to each other at L. The bar J has adownwardly-proj ecting member, J, made either integral with it, as inFig. 1, oradjustable on it, as in Fig. 2. The edge of the tub occupiesthe space between thelower portions of the two clampbars. This space maybe varied in width, according to the thickness of the tubs, in machineshaving theclamp shown in Fig. 2, by adjusting the movable part J uponthe part J, bringing the movable part against the exterior .of the tub,.where it is. held in place, when pressureis applied, by a crampingaction, or v by a fine ratchet beneath the part J, which part may have aterminal projection to retain the movable part. The pivot L, by whichthe members of the clamp are united, passes through a slot, T, in theend piece, O,or may so pass to strengthenthe union of the frame andclamps. -Such slot is an are described from the pivot H. I I l r i Theupper end of the clamp-bar K is curved to form a bearing, upon which theshaft of the lower roller will gradually enter when the' machine istipped down from the position shown in Fig. I to the working, positionof Fig. 2. From these figures it will beobvious 0 that such movementwill lift the lower roll L into forcible contact with the upper one, andby crowding back the'upper endof the piv oted bar K will cause its lowerend to press with much force against the edge of the tub, thus givingsimultaneously the two pressures required. The sides of the slot S actalso as lateralbearings for the lower shaft.

The clothes, entering the machine from the front,'are-kept from gettingbeyond the ends r00 of the rollers by clothes-guards N, formedinpressure and the tub-pressure are alternately tegral with the endpieces, 0, of the frame. applied and released by turning the roller-(See Fig. 3.) carrier frame upon said horizontal pivots,
